Epithelial cells except for the distal portion of the diverticulum were classified morphologically into three typed cells, light, dark and vacuolated. At the end area of each diverticulum, undifferentiated cells were distributed. After 30 days of starvation, the cavity in the midgut gland developed enlarged openings of primary and secondary diverticula which suggesting a drastic change of the construction. Further, a cellular transition from the light cell to the vacuolated cell was indicated in the result of computing estimation concerning the distribution frequency of each typed cell. It was deduced that the light cell was transformed to the vacuolated cell under a critical condition such as long-term starvation.}, pages = {207--213}, title = {Classification of Diverticular Cells of the Midgut Gland in the Prawn Penaeus japonicus}, volume = {36}, year = {} }
